POST OR PILE DRIVER.

@PECIFICATION forming part of Letters Patent No. 371,733, dated October 18,1887.

Application filed April 16, 1887. Serial No. 285,028. (No model.)

.7 0 (LZZ 7117mm, 2'!) 72mg concern Be itknown that I, J osnrn M. BRISTOL, a citizen of the United States, residing at Olean, in the county of Cattaraugus and State of'New York, have invented certain new and useful Improvements in Post or Pile Drivers,- and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same.

Figure 1 is a perspective view of this device. Fig. 2 is a detail in perspective of the hammer; Fig. 3, a detail in perspective of the posthcad support. Fig. 4 shows a modification in the structure of the post and hammer.

This device belongs to that class ofinventions called pile or post drivers; and the novelty consists in'the construction of the uprights; in the adaptation of the upright to its support, whereby it can be placed at any desired angle; in the combination of the hammer with the upright; in the combination of the post head support with the upright; in the construction of the support of the device, whereby the device can be used upon side hills, and in the construction and combination of .the several parts, all as will be now. more fully set out and described, reference being had to the accompanying drawings.

In the drawings, A denotes the sledlike base, and B the upright, which is attached to the cross-bars l3, journaled at its lower ends crosswise in the opposite sides of the sled A. The upright rises at right angles from said cross-bar, and is braced on either side by the metal rods I), which are attached at their lower ends, respectively, to the opposite ends of the cross-bar and at their upper ends to the head or top of the upright B. This construction gives rigidity and permanence to the crossbar in the position above stated.

The hammer G is connect ed with the upright B by means of the metal straps c, which are secured upon the hammer and pass around the upright. Usually these-two straps will answer; but one or more can be used. This at taehment allows free np-and-down movement of the hammer, and the straps act as guides for the movements of the hammer. The hammer is raised by means of the rope-D, which is attached at one end to the eye 0 of the hambolt, a", passes.

mer, and thence, passing over the pulley E in the upper end of the upright, extends down to the deck a of the sled, where it can be operated by hand, by a horse, or by a winch, or by any suitable mechanical contrivance.

The postsupport F is a rectangular frame of suflicient size to fit over the head of any post or pile upon which the machine may be used. It is secured upon the standard B by a strap,f, in like manner as the hammer, as above described, and by this means can be adjusted up or down the post, as desired. \Vhen moved up, it is held by a bolt or pin similar to 6 In order to retain the head of the post or pile within this frame when this machine is being operated, a block, f, is used, which can be set against the head of the pile, and thus retain the post or pile in such position that it will be directly under the hammer and in the right position to receive the hammer squarely upon its head when the pile is being driven.

In order to place the upright in the proper position under all circumstances in relation to the pile or post to be driven, the upright can be moved backward or forward upon its bearings, as aforesaid, and retained in any desired position by means of the metal rod G, which is attached to its upper end in the eye 9, or in any secure way, and at itslower end is adjustably or extensibly held in the sleeve 9' by means of the set-screw g the lower end of said sleeve being secured to the eye g on the frame of the sled or the deck, or in any desired way. It will thus be noticed that the upright may be held in a vertical position or inclined to the left or to the right, as may be desired in use.

In order that the post'drivcr may be adapted for use upon side hills, there is provided a false runner, a, on one or both sides, as may be desired. This false runner has a vertical slot, a near each end, through each of which a headed These bolts at the other end are each fixed in the true runner or side of the sled, and on the outer ends of these bolts setscrews are placed; and so, in leveling up the sled or support on the driver, the false runner can be extended as far as is necessary and then clamped in position. Thus on land of any inclinc the foundation can be placed horizontally level. Horizontally through the upright,

from side to side, are the perforations b, in l which the bolts 1) can be placed, and by means of these bolts thus placed, and so as to come under the guide-straps c, the hammer can be held in any desired position up and down the length of the upright, as may be desired. Likewise by means .of such bolts and these perforations the frame F can be secured in any desired position up and down the upright. The foundation can be held securely and rigidly in any desired position by means of the anchors H, which are attached to the foundation at convenient points.

The device is provided with anchorchains H and I, to give greater firmness and steadiness to the driver when in operation; also, to aid in spacing the distance between the posts.

In Fig. 4. is shown a modification in the structure of the post and hammer, where the face of the post has a central rib, b which fits in the vertical notch c of the hammer. It will thus be perceived that there is produced by this invention a structure which is very simple and very strong and very durable and adapted for very efficient work.

I am aware that in pile-drivers it is not new to provide uprights that can be set at any desired angle with reference to the foundation, and also to provide such uprights with means for holding them at any desired inclination; also that a guide or support for the head of the postin which said uprights may be clamped is not new.

Having now described my invention, whatI consider new, and desire to secure by Letters Patent, is-

1. In a pile driver, the combination of the single upright B, having the hammer 0 secured thereto by the guide-straps c, with the sled A, cross-bar B, brace-rods b, and extensible rod G, substantially as set forth.

2. The combination of the post-head frame F and strap fwith the upright B, substantially in the manner and for the purpose set forth.

3. The combination of the frame F, having strap f, with the post B, having perforations b, and the bolts b and hammer C, substantiall y as described.

4. The combination of the sled or support A with the upright and the operative mechanism and with the false runners (1, whereby the foundation or sled can be set in horizontal position.

5. In combination with the sled A, the false runner at, having slots a and with the bolts a and screw-nuts M, substantially in the manner and for the purpose set forth.

In testimony whereof] affix my signaturein presence of two witnesses.

JOSEPH M. BRISTOL.
